There was a Buizel who had just gotten out of the bookstore with a copy of some fantasy novel that was in a series he'd gotten attached to in the last month.
He decided to take a shortcut home, walking through and ally behind a rundown fruit market. His nose was burried in the book, that was until he heard a sharp growl. The Buizel dropped his book to see a Houndour snarling at him, seeing this, the Buizel would turn around and try to sprint away. He didn't make it too far though, when the Houndour saw him, he lunged forward and tackled the little weasel to the ground. The Houndour barks at the Buizel, stepping into his head with a paw.
"O-ow, fuck! P-please no!" The Buizel begged the Houndour. The Houndour huffed and walked over the Buizel's head, showing off a rather large, dripping canine cock. The Buizel's eyes went wide, he gulping and shaking his head. "W-wait, hold on mutt, I'm n-" but he was cut off by the Houndour slapping him in the face with his canine shaft.
There was Pre on the Buizel's snout, he looking quite pathetic. "Y.. you want me to.. suck it..?" The Buizel whimpers. The Houndour barks, as if to say yes. The Buizel nods, and reluctantly slips his muzzle around the Houndour's member. The Houndour lets out a pleasured yip, and begins to hump the poor little Buizel's face.
He holds the Buizel's head still with his paws while he thrusts in and out of his mouth. The Houndour soon starts to snarl and yelp, signalling that he was about to release. With a final deep thrust, he pushes himself all the way into the Buizel's throat, allowing his canine bulge to reach the back of the Buizel's throat. The Houndour releases, shooting his warm dog juice down the Buizel's throat.
With a 'pop' the Houndour attaches his knot to the Buizel's muzzle, sealing the Buizel's head in place as the Houndour's cock spilled down the Buizel's throat. The poor pup pressed his paw to the Houndour's thigh and tried to push the knot put of his muzzle so he could breath. The Houndour yaps, beginning to slide out of the Buizel's throat. With a gasp the Buizel took in air, but with a sickening slurp the Houndour pushed back into the Buizel's throat, and kept it there.
The Buizel tried to pull away, but the Houndour was just too strong for him. The little weasel began to kick and scream as the powerful beast humped at his face relentlessly.
The Buizel gurgles around the cock as he tried to breath through his nose, the Houndour's unwashed scent was horrible, especially considering the Buizel's nose was forced right into the core of the musk.
After another minute the Houndour released inside the Buizel's throat again, the Buizel coughs and sputters as he tries to get the taste out of his mouth. The Houndour slides out of the Buizel's muzzle with a 'pop'.

The Buizel's head flopped to the floor as he choked up doggy cum, trying to also breath in something that wasn't Houndour musk.

The Houndour sat down, watching the Buizel with a smile. The little weasel just lay there, exhausted from his ordeal. 
The Houndour would press his hips against the poor Buizel's nose.
Musk would begin to fill the Buizel's nostrils again as the scent drove him into a tizzy.
His mouth beginning to water as he licked his chops.
The little weasel turned away from the houndour's bulge, blushing very deeply, he was feeling very embarrassed about being in his situation... And even more so for somehow enjoying it.
The Houndour would bark at the Buizel, roughly nudging his head against the poor pup's side.
The Buizel tried to protest, but he knew what the Houndour wanted. With a gulp, he began to lap at the Houndour's sheath. The taste was bitter and salty, and the texture was rough. It reminded him of eating peanuts out of the shells.
As he did this, the Houndour began to wag his tail. The Buizel looked up at him, still blushing. The Houndour barked, nudging his head against the Buizel's head gently. The Buizel looked up at the Houndour as he began to lap faster.
The Houndour would begin to pant, he started to like this pup's service a little too much. 
The Buizel started the crave the musky taste the the Houndour's balls. He wanted to take all of it in his mouth.
The Houndour's legs began to tremble, he was going to release soon. The Buizel didn't want to swallow any more cum. He tried to be a clean Buizel and didn't like not being able to breath.
He began to whimper as he started to struggle away, the houndour would bark and growl at him, keeping him in place. He wanted to finish.
The Houndour released with a powerful thrust into the Buizel's muzzle, forcing his knot into the little weasel's muzzle.
The houndour released inside the Buizel's mouth and the Buizel felt his stomach begin to churn. The musky taste of the houndour's jizz was becoming too much to bare.
The little weasel began to gag and splutter and with another harsh thrust from the Houndour, cum shot out of the Buizel's nose.
The Houndour barked in annoyance, he didn't like the Buizel wasting his seed. The houndour let go of the Buizel's head, allowing him to pop the knot out of his muzzle and fall into his back, panting and trying to get air into his lungs.
The Houndour looked over as he was licking his own shaft clean, seeing the Buizel's perfectly virgin ass. He smirked, the Houndour had plans for that little hole.
The Buizel didn't even see it coming. The houndour pounced on the Buizel, knocking him over and pinning him to the ground with his paws. The little weasel squeaked, too tired and exhausted to put up a fight.
The Houndour lined up his prick with the Buizel's hole, pushing inside with one quick thrust. The little weasel cried out in pain as the Houndour's knot expanded in his tunnel, blocking him from exiting.
The houndour began to thrust into the Buizel's hole, his paws against his hips, pinning him down against the cold floor.
The Houndour grunted with each thrust as the Buizel cried out in pain.
He tried to stay quiet, but he was failing horribly.
The houndour's teeth were bared as he panted and groaned, his thrusts became quicker and more bestial. He was reaching his climax.
The Buizel felt the knot inside his tunnel expanding even more, beginning to push into his exit. He whimpered and cried, wishing this ordeal would end.
The houndour began to pant heavily, his seed releasing deep inside the little weasel's tunnel.
Squeaking out in the shock of his no longer virgin ass being taken, the Buizel gripped the Houndour around the neck for support and scrunching upward in pain.
He felt the houndour's hot breath on his back and neck as he panted.
He also felt something dripping from the Houndour's mouth, it was the mutt's drool.
He licked the Buizel's ears and neck, his tongue rough like sandpaper.
The Houndour was still thrusting into the Buizel's used tunnel, his paws wrapped around the little weasel's waist.
The Buizel couldn't help but enjoy the feeling of being dominated in such a way, it was... Intoxicating. He wanted more.
It was at that moment that the Buizel shot up in a moment of heat and kissed the Houndour.
The Houndour was surprised, but kept didn't want to stop fucking. He began to thrust in a rhythmic motion as the two started to make out.
The Houndour's tongue entered the Buizel's mouth and and went down his throat.
The second the Buizel felt the tongue push into his throat, he gasped out in a squeaky tone and thrusts his hips up as he cums all over the Houndour's under belly and his own stomach.
The Houndour didn't mind the warm feeling, he wanted to fill the little weasel up. He continued to thrust and pump his hips, pushing his knot inside the Buizel's tunnel.
The Buizel cried out in pleasure as his tunnel began to feel the houndour's knot pop in and out of it. His paws gripping the floor as he squeaked out.
The Houndour pulled away from the kiss and pulled his knot out of the Buizel's ass. The Houndour then moved forward, still with an attentive shaft. He pushed the Buizel into the puddle of jizz he shot out earlier, grabbing him by the head and shoving his knot into the weasel's mouth.
The houndour's knot entered the Buizel's muzzle and down his throat. The little weasel gagged and choked as he felt it expand down his throat, pushing deeper and deeper as he tried to pull away.
Unfortunately, the Buizel wouldn't be taking another load of pent up doggy cum, instead the Houndour starts pissing down the Buizel's throat.
The Buizel's eyes widen as he begins to drown from the warm doggy urine, the Houndour still pissing into his mouth and esophagus. He gags and coughs as the urine fills his lungs, drowning him.
After a few moments, the Houndour pulls his knot out of the little weasel's head with a plop. The Buizel lays on the floor motionless as the Houndour looks down at him with a smirk. The Houndour wipes his cock off on the Buizel's fluffy cheek and then his ears perk up.
The Houndour can hear the Buizel's breathing and thinks about finishing him off, but decides against it. 
The Houndour smiled and started walking away from the recovering Buizel, wondering if the Buizel would ever 'accidentally' walk into his territory again.
